FYI, I originally tried the solid connection adaptor as Mike has shown. But the Dupree dump valve and connector on coach 540 is too close to the hole in the floor where the hose connects. As such, it simply doesn't fit with a Valterra hose connected, no matter how short you make the Valterra side. You should try a dry fit or just an eyeball of everything to make sure it will work. I ultimately had to go with the short section of sewer hose option.
